Sorry but dyno pack is BS. Wheels off and measuring off the hubs? Do you drive on the hubs??
It's an easy 50 - 60 hp increase. Heck you sure can't say rwhp.
Put that same car on a DJ or DD and see what gives.
480 "rear hub" hp with those mods ... sorry but do not think so.
Sorry I'm just an a-hole who just believes on the facts.
Better yet, to hell with the "dyno pack". Run another M5 or M6 with same mods or an RPI tuned M5/M6. End of story. The dyno is BS. What counts is what happens on a straight up run.

Obviously an uneducated person here with no idea how the dynapack works. We are +/- 5whp with all dynojets around here. Did you forget that Dinan uses a dynapack?

don't want to say that dyno isn't realistic, but with headers i made 490whp.

We made 499whp with a bolted / tuned M6 with headers, it was 110 degrees and the car would flatten out up top due to coolant compensation so it's possible there was more in it. On a cooler day the same M6 used our local dynojet and made 509whp SAE.

Is that Sizzle's M6 or was it the M6 that ran super lean on the 509 whp pass?
